From a Congressional committee hearing today about technology in the Court system:
Justice Scalia: “I don’t know even what it is . . . I’ve heard it talked about”
Justice Breyer: “remember when they had that disturbance in Iran . . . there were some Twitters as I call them . . . but there were people there with photos as it went on . . . it’s instant and people react instantly . . . it’s not something that’s going to go away”
Well, at least they didn’t call it a series of tubes.

I’d place this on the list of Top Ten Things to Not Give a Rat’s Ass About.
If there ever comes a time where learning about Twitter is immediately relevant to what they need to do, then I’m sure they could do it.
